Since ἵημι is reduplicated (probably for σι-ση-μι) the initial ι should be short, as it is in Hom. (rarely in Attic poetry). ι_ is probably due to confusion with the ι_ of Hom. ἵ_εμαι (ϝί_εμαι) strive, a meaning that ἵεμαι occasionally shows in Attic. ἵεμαι meaning hasten occurs only in the present and imperfect.
